I just bought a Sony HX300. The viewfinder is very fuzzy - so bad it is not usable. Gordon Laing stated in his review of the camera that the viewfinder can be adjusted to someone's eyesight. Nowhere on Sony's website, the manual, the on-camera guidance or any other reference on the Internet can I find how to make any adjustment. Help!

On the left of the viewfinder, there should be a small round dial. Turn that until the indicators in the viewfinder (e.g. focus points, or the numbers along the bottom) look sharp. Don't try to get the actual image sharp, just focus on the indicators.
